WOW... 8O
That is indeed a gorgeous Fiolet in excellent condition.
I echo what Lonestar and Zuni said about the meerschaum. It'll be fragile. If the band's got a hallmark, it's silver. But the absence of one does not rule out it being silver. Not all countries subscribed to hallmarking silver.
I'm glad as well you are deciding to keep them. They're gorgeous family heirlooms. Certain stores can actually put them in a shadowbox for you so you can hang them on the wall. Michael's, Hobby Lobby, those kind of places can do it.
On the cob.. oh well.. what is done is done. I'm not a cob expert so I'll let others chime in on whether there is such a thing as the holy grail of cob pipes ;-)
Gorgeous finds, excellent stuff.. thanks so much for sharing and get them framed, boxed and hang them on the wall for many years to come !
